Abstract: PURPOSE:To obtain a uniform thermally sprayed layer in which the surface of the thermally sprayed layer is reduced to a rugged one to such a degree that it is not too rough by specifying the particle size distribution of ceramic particles to form a thermally sprayed layer. CONSTITUTION:The surface of a ferrous base metal such as an iron cover for a manhole is thermally-sprayed with ceramic particles to form a ceramic thermally sprayed layer. At this time, as 50 to 80wt.% of the ceramic particles, the ones having 10 to 50mum, preferably 15 to 40mum particle size are used. As the ceramics, Al2O3, Al2O3-TiO2 or the like are used. As the thickness of the thermally sprayed layer, about 100 to 300mum is sufficient. Furthermore, according to necessary, before the ceramic thermally spraying, the thermally sprayed layer of corrosion-resistant metals is formed on the surface of the ferrous base metal to prevent rusting. If required, the formed ceramic thermally sprayed layer is subjected to sealing treatment by a synthetic resin sealing material. By this method, the generation of the clogging of a thermal spraying nozzle is reduced, and excellent workability can be obtd.

Abstract: PURPOSE:To improve the corrosion resistance of a susceptor to a mixed gas for vapor phase etching, and to increase the life use number of the susceptor by forming an oxide film consisting of silicon onto the surface of an silicon carbide film. CONSTITUTION:The surface of a carbon base material 1 is coated with an silicon carbide film 2, and an oxide film 3 composed of silicon is shaped onto the surface of the silicon carbide film 2. The oxide film 3 may also be formed by oxidizing a conventional silicon carbide film and shaping an oxide film made up of SiO2 onto the surface of the silicon carbide film. It is preferable that the thickness of the oxide film 3 extends over 5-1000Angstrom , the effect of the improvement of corrosion resistance is reduced when the thickness of the oxide film extends over 5Angstrom  or less, and thermal conductivity from a susceptor is minimized and cracks or peeling is easy to be generated in the silicon carbide film 2 or the oxide film 3 from the difference of the thermal expansion coefficients of silicon carbide and the oxide film 3 before the temperature control of a wafer 4 becomes difficult when the thickness of the oxide film extends over 1000Angstrom  or more. Accordingly, the corrosion resistance of the susceptor to a mixed gas for vapor phase etching is enhanced, and the life use number of the susector can be increased.
